There should be a wiring diagram on the inside of the cover. It is imperative though that you get the wiring done by a qualified electrician. The thermostat has a single pole changeover contact and two separate terminals that go to each end of a 240V neon pilot light which you can wire up in any configuration independly of the switch contacts. Contact us at Cookson Controls in Adelaide if you have any more questions.

Thermostat wire color codes
explained.Please note. Not all installers use the proper color codes when they
install or replace equipment. It may be necessary go go to the furnace or
outdoor unit to verify what wires are for what purpose. Also be sure there are
no splices in the wire that could change the wire colors between components.

R (red)
or Rh (Red heat) 24 volts from equipment.

Rc (Red
cooling) 24 volts from transformer in cooling equipment.

Note: If only furnace has a
transformer and cooling equipment does not jumper Rc and Rh.

W (White)
sends 24 volts to furnace control to start the heating cycle.

ok the black wire from the powersource goes to the (-)negative terminal in the converter, the white wire goes to the (+) positive.
From the converter the white wire goes to the white wire on the termostat.
the thermostat black wire goes to the grey wire on the condenser
the blue wire on the condenser goes to the black wire on the Conveter.
